A DigitalOcean Droplet is a Linux virtual machine, not a managed Next.js runtime. The move succeeds when the team deliberately replaces Vercel’s deployment, scaling, networking, observability, and service integrations, not when a Node process merely starts on port 3000.
Provision for replacement, not repair in place
Choose the region near users and stateful dependencies. Use SSH keys, attach the Droplet to the intended VPC, enable improved metrics, and apply a Cloud Firewall by stable resource tag when replacement instances should inherit policy. Review every firewall attached to the Droplet because DigitalOcean applies the union of their allow rules.
Run Next.js as an unprivileged supervised process behind a reverse proxy. Keep immutable release directories or images so rollback does not depend on rebuilding during an incident. Decide whether a Reserved IP, load balancer, or DNS record is the stable traffic boundary before cutover.
Prove operations and recovery
Trigger alerts, stop and restart the process, validate TLS renewal, and restore a backup to a separate Droplet. Provider monitoring and disk images are useful controls, but they do not replace application logs, transaction checks, database recovery, or external service reconciliation.
Test the candidate using the production hostname before changing public DNS. Verify streamed responses are not buffered, image optimization has enough memory, caches survive as intended, and shutdown drains in-flight work.
Cut over with a written abort rule
Record the exact old and new DNS values, lower TTL early, and assign one decision owner. Watch resource saturation and user outcomes after the switch. A rollback restores traffic to Vercel; it does not automatically undo writes or external events created while the Droplet was active, so reconciliation is part of the runbook.
